Hair-loss protocol
A two-part system to protect and support your hair.
The protocol pairs a clinician-prescribed daily pill with Hatsy's SilkTech™ hat — addressing both the biological and mechanical drivers of hair loss in one simple routine.
Starting at $149/mo · includes consult, hat, shipping and medication if approved. Prescription medication. Medical evaluation required.
Compounded medications used in the hair-loss protocol are prepared by our partner FDA-registered 503A/503B pharmacy. Compounded medications are not FDA approved and are not generic equivalents of any brand-name drug.
Two parts, one routine
Pill
Finasteride and minoxidil block DHT and feed the follicle, with biotin, D3 and K2 to support healthy hair growth.
SilkTech™ Hat
Hatsy's silk lining eliminates the friction and traction that cause mechanical hair loss — wear it like any cap.
Two mechanisms. One result.
Hair loss isn't one problem — it's two. A hormonal driver thinning follicles from the inside, and daily mechanical wear breaking them from the outside. The pep'd protocol addresses both.
Inside the pill
Finasteride
A 5-alpha-reductase inhibitor that blocks the conversion of testosterone into DHT — the androgen most responsible for miniaturizing scalp follicles in male-pattern hair loss.
Minoxidil
A vasodilator that extends the anagen (growth) phase of the hair cycle and increases follicular blood flow, encouraging thicker, denser regrowth.
Biotin, Vitamin D3 & K2
Cofactors that support keratin production, follicle signaling, and the nutrient delivery your hair needs to actually use what the Rx is doing.
Inside the SilkTech™ hat
Grade 6A Mulberry silk
The highest silk classification — the same grade used in luxury bedding and medical-grade applications. Not satin. Not a blend.
Near-zero friction
Silk's smooth fiber surface eliminates the micro-abrasion that cotton and synthetics create against the hairline and crown every hour a hat is worn.
Thermo- and moisture-balanced
Silk breathes and wicks instead of trapping heat and sweat, keeping the scalp environment closer to its natural state — less irritation, fewer clogged follicles, no hat acne.
*Based on a survey of 200 Hatsy customers after 30 days of daily use.
"The silk lining isn't a gimmick — it's the same principle I tell every patient who asks how to protect their hair while living their life."
